In comparison to conventional fuels, vehicles using renewable fuels would have lower carbon emissions [2]. The European Commission has introduced a biofuel production plan. Alternate fuel,such as biodiesel, has been used for 10% of conventional fuels in Europe by 2020, according to this plan [3]. First-generation biodiesel, a mixture …
The process plant economic evaluation was based on the Chemical engineering plant cost index (CEPCI). It was also applied in the methodology of capital cost estimation to determine the chemical plant construction cost (Lozowski et al. 2012; Yeo et al. 2018). However, the purchase cost calculated by the Lang factor is a rough …
